The invention provides a low-fat health care chicken sausage prepared by utilizing compound hydrophilic gel and chicken skin to substitute fat and a method thereof, which belong to the technical field of deep processing of poultry. The low-fat health care chicken sausage prepared by utilizing the compound hydrophilic gel and the chicken skin to substitute the fat is characterized in that the chicken sausage takes chicken and the chicken skin as main raw materials; and auxiliary materials comprise transglutaminase, hydrophilic compound gel, composite phosphate and soybean protein isolate. Preparation working procedures comprise pickling, the pre-treatment of enzyme solution, the pretreatment of hydrophilic gel, cutting and mixing, enema exhaust, reaction, drying and boiling. The chicken sausage has the advantages of simple production technology, broad raw materials and low cost, and overcomes the disadvantage of the decrease of the quality caused by low fat. At the same time, serial low-fat health care chicken sausage products with various tastes and various nutritions can also be developed based on the low-fat chicken sausage.

The present invention relates to a BTF used for dealing with the volatile waste gas, belonging to the field of treatment of the volatile waste gas, which aims at solving the problems that the prior BTF has uneven air flow distribution and biomass distribution, high center gas speed and voltage drop, and the prior BTF is easy to be blocked. The technic proposal is that: the volatile waste gas passes through an intake pipe (1) and then comes into a biofilter (22), and then being drained away by an exhaust pipe (9) after having the processes of degradation and purification; a nutrient solution (11) comes into the biofilter (22) through a nutrient solution shower (18) and a dropwise adding distributor device (19) having fixed quantities at fixed time; the present invention is characterized in that adopting a light and cheap packing (4) with different grain diameters, the biofilter (22) takes a homocentric column shape sleeve structure , the grain diameters of the filled packing (4) from the center to the edge are distributed from small to big, the centre area is filled with the packing (4) with small grain diameters, the ring area of the around close walls is filled with the packing (4) of big grain diameters. The present invention makes the distribution of the biomass in the biofilter even, thereby fully utilizing the useful space of the biofilter.

The invention discloses a lead-acid storage battery positive lead paste. The lead-acid storage battery positive lead paste is prepared from the following raw materials in parts by weight: 70-90 partsof lead powder, 3-15 parts of sulfuric acid, 5-20 parts of water, 0.05-1 part of short fiber, 0.05-0.5 part of graphite and 0.05-0.5 part of xanthan gum. A lead-acid storage battery prepared by usingthe positive lead paste is high in initial capacity, slow in attenuation and long in cycle life, has strong large current discharge and low temperature charge and discharge performance, and ensures that the combination performance of the lead paste and a grid is significantly improved; and the problems of low initial capacity, short cycle life, easy falling off of active materials and the like inexisting lead-acid storage batteries can be effectively solved.

The invention provides a novel chicken block taking hydrophilic compound gel and soybean protein as functional auxiliary materials, which belongs to the technical field of deep processing of poultry. The novel chicken block taking the hydrophilic compound gel and the soybean protein as the functional auxiliary materials takes chicken and chicken skin as main raw materials; and the auxiliary materials comprise transglutaminase, hydrophilic compound gel, composite phosphate and soybean protein isolate. Preparation working procedures comprise pickling, the pre-treatment of enzyme solution, the pretreatment of hydrophilic gel, cutting and mixing, molding, reaction, rebaking, tabletting, battering and breading, and frying. The novel chicken block has the advantages of simple production technology, broad raw materials and low cost, and overcomes the disadvantage of the quality of products produced by chicken raw materials. At the same time, serial chicken block products with various tastes and various nutritions can also be developed based on the novel chicken block.

The invention discloses a preparation method of a dope for metal type casting of a magnesium alloy thin-walled component. The dope comprises the following components in percentage by weight: 1.5 to 2.5 percent of kieselguhr, 2 to 3 percent of magnesium oxide powder, 1.2 to 1.8 percent of titanium dioxide powder, 1 to 2 percent of zirconite powder, 1.5 to 2.5 percent of bentonite, 2 to 4 percent of asbestos powder, 1.2 to 1.4 percent of silica sol and the balance of alcohol. The preparation method comprises the following steps of 1) weighing the materials according to the proportion; 2) taking 30 percent of the total alcohol, adding the bentonite into the alcohol, stirring until the bentonite is suspended, sequentially adding the magnesium oxide powder, the titanium dioxide powder and the zirconite powder into the suspension, and stirring the suspension for about 15 to 25 minutes to uniformly mix the materials and obtain a mixture I; 3) mixing and stirring the kieselguhr, the asbestos powder and the silica sol for about 10 to 20 minutes, adding 20 percent of the total alcohol into the mixture, and stirring the materials for about 5 to 15 minutes to uniformly mix the materials and obtain a mixture II; and 4) mixing the mixture I, the mixture II and 50 percent of residual alcohol, and stirring the materials for about 20 to 30 minutes to obtain the dope.

Belonging to the technical field of oil-gas well cementing, the invention discloses a low-density oil well cement. The oil well cement comprises the following raw materials by weight percentage: 82-90% of cement clinker, 1-8% of gypsum, 5-10% of hollow glass beads, 0-0.3% of a dispersant, and 0.5-0.8% of a retarder. The cement clinker is one of sulphate aluminium cement clinker and high belite sulphoaluminate cement clinker.
